About the Logging action
The Logging action can be used in an access policy or in a per-request policy. In an access policy, the Logging action adds logging for session variables to the access policy. In a per-request policy, the Logging action can add logging for both session variables and perflow variables to the per-request policy.
This action is useful for tracing the variables that are created for a specific category, or in a specific branch.
A session variable might or might not exist at the time of logging; depending on the result of the access policy branch, or results of processing the access policy.
The Logging action provides these configuration elements and options:
- Log Message
- For an access policy, specifies text to add to the log file. For a per-request policy, specifies the message text and the session and per-flow variables to add to the message. Complete variable names must be typed. Wildcards are not supported for per-request policies. An example log message for a per-request policy follows.The system found this URL %{perflow.category_lookup.result.url} in these categories %{perflow.category_lookup.result.categories} and placed it into this category %{perflow.category_lookup.result.primarycategory}.An HTTPS request was made to this host %{perflow.category_lookup.result.hostname}; the per-request policy set SSL bypass to %{perflow.ssl_bypass_set}.Requests from this platform %{session.client.platform} were made during this session %{perflow.session.id}.
- Add new entry
